Emergency contraceptive pills are only taken orally within 72 hours after coitus, which can play a contraceptive role in the last coitus. If you take the pills and then coitus, it is recommended that it is possible, but you must use a condom to contracept, which ensures the safety of contraception. In addition, it is recommended that the emergency contraceptive pill should not be used as a regular contraceptive method, because the progesterone content of the emergency contraceptive pill is very high, not only can inhibit the normal ovulation of the ovaries, breaking the natural ovulation pattern of the ovaries, but also may cause damage to the liver and kidney function, so it is best not to take the emergency contraceptive pill frequently. It is recommended that if you do not intend to get pregnant within a long period of time, it is recommended that you can go on the intrauterine device for contraception, and if you don’t want to get pregnant within a short period of time, it is best to use a condom for contraception.
